Darken specific apps by overlay

(I got this suggestion via email -- I'm writing down a summary here for reference)
It would be interesting if we could darken specific apps or even windows using a semi-transparent dark overlay. The result might be less contrast between dark and light windows. It also won't suffer from the delays of changing monitor brightness.
There is a disadvantage: Lumen might save some power by allowing you to use a lower brightness when using apps with a light background, while using apps by overlay might make you keep your LCD brightness higher.
Darkening via overlay seems like something technically feasible in macOS. Some related things:
